Definitions
- the present invention relates to an improvement of a bill discrimination apparatus, more particularly to easy opening/closing operation of a bill feeding passage for the maintenance of bill discriminating means, comprising optical sensor, magnetic head, etc. disposed adjacent to the bill feeding passage or facile removal of a jammed bill from the bill feeding passage.
- the bill feeding passage in a bill discrimination apparatus normally consists of a pair of bill feeding plates disposed opposite to each other by being spaced with a predetermined gap, and is equipped with a bill conveyor means comprising belts and rollers and various detecting means, e.g. magnetic head and optical sensor, for discriminating genuine or counterfeit with respect to a bill used.
- a bill conveyor means comprising belts and rollers and various detecting means, e.g. magnetic head and optical sensor, for discriminating genuine or counterfeit with respect to a bill used.
- a long term use of the bill discrimination apparatus causes contamination adhering on belts and rollers, which tends to induce bill slippage, or causes contamination on magnetic heads or optical heads which may disable the normal bill discriminating function. Furthermore, there is a possibility that the bills are jammed during conveyance through the bill feeding passage.
- the object of the present invention in view of above-described problems or disadvantages of the prior arts, is to provide a bill discrimination apparatus which is capable of easily opening or closing the bill feeding passage with simple one-motion operation.

- the bracket 49 supports this rotational speed detector 61.
- an actuation of the DC motor M1 causes a rotation of the pinion gear 50, whose rotation is transmitted to the worm gear 53 through the large diameter gear 51a and small diameter gear 51b of the stepped spur gear 51 and the spur gear 52. Then, the rotation of the worm gear 53 is transmitted to the worm wheel 54 to rotate the drive shaft 55, thereby causing a rotation of the drive shaft 55 and each drive timing pulley 38 fixed on the drive shaft 55.
- the drive timing pulley 38 cooperates with the driven timing pulley 37 to rotate an endless timing belt 39 wound around them.
- a pair of pinch rollers 41, 41 is provided below the second bill feeding plate 34 between the driven and drive timing pulleys 37, 38.
- the pinch rollers 41, 41 are spaced providing a predetermined distance in a widthwise direction and disposed in parallel with each other.

- the second bill feeding plate 34 is provided with two sets of light emitting elements 72, 72 and 73, 73, respectively corresponding with the positions of the photoelectric converters 68, 68 serving as a part of the optical sensor for detecting an insertion of bill and the photoelectric converters 71, 71 serving as a part of the bill passage position detecting sensor.
- an automatic return pull-type solenoid 74 Located a little bit downstream from the magnetic head 70 along the bill insertion direction is an automatic return pull-type solenoid 74, which is fixed through a bracket 77 to the casing 67.
- This solenoid 74 comprises an automatic return spring cooperative with its movable core.
- This automatic return spring allows the movable core to protrude downward when the solenoid 74 is deactivated, while the movable core retracts when the solenoid 74 is activated.
- This movable core of the pull-type solenoid 74 has a distal end fixed to a shutter member 75.
- This shutter member 75 has bifurcated ends 75a, 75a, which are fabricated through the press working and will be explained in more detail with reference to Figs. 8(a) - 8(b).
- the shutter member 75 further includes an integrally formed shielding plate 75b.

- the shielding plate 75b is interposed between the photoelectric converter and the light emitting element of the shutter sensor 78.
- the shielding plate 75b goes out of the interspace between the photoelectric converter and the light emitting element, while the shielding plate 75b comes between the photoelectric converter and the light emitting element when the bifurcated ends 75a, 75a of the shutter member 75 is between the first bill feeding plate 33 and the second bill feeding plate 34, or when the bifurcated ends 75a, 75a retract above the slits 76 of the first bill feeding plate 33.
- the shutter sensor 78 detects the shielding plate 75b when the pull-type solenoid 74 is activated to completely retract the bifurcated ends 75a, 75a of the shutter member 75 above the slits 76 of the first bill feeding plate 33 and when downward movement of the bifurcated ends 75a, 75a from their retracted positions in response to the deactivation of the pull-type solenoid 74 to enter into the slits of the second bill feeding plate 34 is prevented due to the presence of a bill and the like.
- the shutter sensor 78 does not detect the shielding plate 75b when the bifurcated ends 75a, 75a of the shutter member 75 extend downward below the slits of the second bill feeding plate 34 through the bill feeding passage 31.
- Fig. 8(a) is a plane view
- Fig. 8(b) a right side view
- Fig. 8(c) a front view.
- these plane, right side, and front views respectively show only the relative positions within these and Figs. 8(a) - 8(c), and therefore it should be noted that they have no correlation with each drawing of Figs. 1 to 7.
- This shutter member 75 made of metal plate by press working, has a base plate 75c secured to the movable core of the pull-type solenoid 74 by rivet or brazing means.
- Previously described bifurcated parallel ends 75a, 75a are formed by bending both ends of this base plate 75c to extend almost perpendicularly.
- an extension arm 75d extends from this base plate 75c toward the other end like a tongued piece. The front end of this extension arm 75d is bent perpendicularly in a direction opposite to the bifurcated ends 75a, 75a to form the previously explained shielding plate 75b.
- Each of bifurcated ends 75a, 75a has round cutouts 70a, 79b at both edges of its middle portion as shown in Fig. 8(d). At the points on both sides closer to the distal end than the cutouts 79a, 79b, these are provided a round projection piece 80a and a sharp wedge-shaped projection piece 80b.

- This bill feeding plate opening lever 82 integrally formed of synthetic resin material having high elasticity and tenacity, has a lower end formed into an engaging hook 83 and an upper end formed into an operating projection 84.

- Fig. 7(b) is a rear view showing the bill feeding plate opening lever 82 itself. It should be noted that Figs. 7(a) and 7(b) have different contraction scales.
- the bill feeding plate opening lever 82 includes a rectangular plate portion 85, extension arms 86, 86 extending downward from both ends of the plate portion 85, an operating projection 84 formed along a longitudinal direction of the plate portion 85 and extending upward and rearward from the center thereof to form an arc shape, and two bearing pieces 87, 87 formed at the front end of the plate portion 85 being spaced providing predetermined distance in the longitudinal direction.
- the engaging hook 83 formed at an end of the extension arm 86, has a tapered guide surface 88. Round cutouts 89, 89, for preventing crack, are formed at corners between the plate portion 85 and extension arms 86, 86.
- the casing 67 has a shaft 90 fixed at a place slightly inside from the distal end thereof as shown in Fig. 6(a).
- the bearing pieces 87, 87 of the bill feeding plate opening lever 82 are coupled around this shaft 90, while the extension arms 86, 86 of the lever 82 grip both side ends of the casing 67.
- the bill feeding plate opening lever 82 is rotatably installed at the swingable distal end of the casing 67 as shown in Figs. 6(a) and 6(b).
- a coil spring 91 is wound around the shaft 90. This coil spring 91 urges the lever 82 in a clockwise direction as shown in Figs. 6(a) and 7(a). Swing motion of the bill feeding plate opening lever 82 in the clockwise direction is restricted within a limit shown in Fig. 7(a) due to interference between the lower edge 92 of the plate portion 85 and the upper edge 93 of the distal end of the casing 67.
- the right and left side plates 3, 4 constitute an exterior of the bill discrimination apparatus 1.
- a substantially rectangular engaging piece 94 which engages with the engaging hook 83 of the bill feeding plate opening lever 82 when the casing 67 is closed to form a predetermined gap between the first and second bill feeding plates 33, 34 as shown in Fig. 7(a).

- the bottom of the casing 67 i.e. the first bill feeding plate 33, is prevented from being lifted up.
- the guide rollers 69, 81 disposed on the first bill feeding plate 33 are pressed by means of spring force against the timing belts 39, 39 disposed on the side of the second bill feeding plate 34. Furthermore, the pinch rollers 41, 41 disposed on the side of the second bill feeding plate 34 are pressed against the magnetic heads 70, 70 disposed on the side of the first bill feeding plate 33, thereby enabling the insertion of a bill, automatic feeding of the bill, and reading information from the bill for discrimination. That is, normal operation of the bill discrimination apparatus 1 can be executed.
- the bill feeding passage 31 can be widely opened by pulling up the operating projection 84 of the bill feeding plate opening lever 82 with one's finger to swing the lever 82 in a counterclockwise direction as shown in Figs. 6(b) and 7(a).
- This lifting action will not immediately be followed by the swing motion of the swing unit 8 because the engaging hooks 83, 83 will still remain engaged with the engaging pieces 94, 94 of the right and left side plates 3, 4.
- This pulling force gives the bill feeding plate opening lever 82 a rotational moment about the bearing pieces 87, 87 in the counterclockwise direction.
- the operating projection 84 of the bill feeding plate opening lever 82 is positioned behind (i.e. right-hand side in Fig. 7(a)) the bearing pieces 87, 87 which serve as a swing center of the lever 82.
- the rotational moment acting about the bearing pieces 87 in the counterclockwise direction will cause the bill feeding plate opening lever 82 to swing in the counterclockwise direction to disengage the engaging hook 83 from the engaging piece 94.
- the swing unit 8 will be released from locked position, and the lifting force given to the bill feeding plate opening lever 82 comes to directly act on the swing unit 8 as a rotational moment acting about the hinge shaft 36 in the counterclockwise direction.
- the swing unit 8 will be caused to make a swing motion in the counterclockwise direction as shown in Figs. 6(b) and 7(a). Therefore, the first bill feeding plate 33 formed at the bottom of the casing 67 separates from the second bill feeding plate 34 to open the bill feeding passage 31.
- the lifting force given to the bill feeding plate opening lever 82 not only causes the lever 82 to swing around the bearing pieces 87, 87 in the counterclockwise direction to disengage the engaging hook 83 from the engaging piece 94 but simultaneously causes the casing 67 to rotate about the hinge shafts 36, 36 in the counterclockwise direction to open the bill feeding passage 31, so that releasing the engagement of the first bill feeding plate 33 and lifting the same can be done simultaneously by simply lifting up the operating projection 84.
- the swing center of the opening lever 82 of the bill feeding plate is positioned at an outside (i.e. a right side in Fig. 6(b)) of the hinge shafts 36, 36 which serve as a swing center of the casing 67; the bill feeding plate opening lever 82 is swung outward to disengage the engaging hook 83 from the engaging piece 94; the position of the operating projection 84 can be freely selected as long as it is positioned at an outside, i.e., right side in Fig. 6(b), of the swing center of the lever 82.
- the swing unit 8 For closing the bill feeding passage 31, the swing unit 8 is pressed downward from the opening position (a phantom line in Fig. 6(b)) as is shown in the clockwise direction in Fig. 6(b); this first cause the bill feeding plate opening lever 82 comes into contact with upper end of the engaging piece 94 at its tapered guide surface 88. By further rotating the swing unit 8 in the clockwise direction, the tapered surface 88 is gradually pressed by the engaging piece 94. As a result, the bill feeding plate opening lever 82 rotates in the counterclockwise direction to cause the engaging hook 83 to ride on the engaging piece 94.
- the swing unit 8 Further rotating the swing unit 8 will cause the engaging hook 83 to finally get over the engaging piece 94 to automatically enters the coupling recess formed under the engaging piece 94, being assisted by the urging force of the coil spring 91 acting in the clockwise direction. Consequently, the casing 67 engages with the engaging pieces 94 formed on the side plates 3, 4 through the bill feeding plate opening lever 82. In this condition, the bill feeding passage 31 is formed between the first bill feeding plate 33 constituting the bottom of the casing 67 and the second bill feeding plate 34 fixed to the side plates 3, 4. In this manner, the closing operation of the swing unit 8 for forming the bill feeding passage 31 can be carried out by the complete one-touch operation.
- the closing operation of the swing unit 8 can be executed not only by pressing down the swing unit 8 but pressing down the operating projection 84 of the bill feeding plate opening lever 82.
- the pressing force given to the operating projection 84 prevents the bill feeding plate opening lever 82 from rotating in the counterclockwise direction when the engaging hook 83 encounters with the engaging piece 94.
- the extension arm 86 having high elasticity and tenacity can elastically deforms to bend rearward.
- the retracting motion of the engaging hook 83 and the motion of the engaging piece 94 for reentry into the recess can be realized.
- a micro processor contained in the control box 10 executes circuit check and initialization while the DC motor M1 is driven for a predetermined time. During this period of time, the micro processor counts the number of pulse the rotational speed signal outputted from the rotational speed detector 61, in order to judge whether or not the speed of the timing belt 39 constituting the bill conveyor means is maintained within an appropriate speed range.
- An adequate bill feeding speed is guaranteed only when the value counted during a predetermined time is in an allowable range. Thus, when this condition is fulfilled, the micro processor is then conditioned to wait an insertion of a bill. On the contrary, if the counted value is out of the allowable range, the micro processor judges that the bill feeding speed is not adequate due to some king of malfunction and stops the DC motor M1 to interrupt all the operations after generating alarm.
- the processing in the case where the adequate bill feeding speed is guaranteed.
- the inside surface of the upper bezel 14a, the inclined surface of the coupling member 25, and the rib 32 formed inside the front mask 2 cooperatively guide the front end of the inserted bill, thereby causing the bill to be fed into the bill feeding passage 31 formed by the first and second bill feeding plates 33, 34.
- the bill insertion sensor consisting of the light emitting element 72 and the photoelectric converter 68 operates to output an insertion detecting signal to the micro processor.
- the micro processor causes the DC motor M1 to rotate in a forward direction to initiate the bill feeding operation by the timing belts 39, 39 and the guide rollers 69, 81.
- the bill pressed between the timing belts 39, 39 and the guide rollers 69, 69, is conveyed in the previously described bill insertion direction.
- the bill passage position detecting sensor consisting of the light emitting element 73 and the photoelectric converter 71 generates an ON signal.
- the micro processor synchronously responds to this ON signal and activates the pull-type solenoid 74 so that the bifurcated ends 75a, 75a of the shutter member 75 retract from the bill feeding passage 31.
- the bill insertion sensor consisting of the light emitting element 72 and the photoelectric converter 68
- the bill passage position detecting sensor consisting of the light emitting element 73 and the photoelectric converter 71, detect and cooperatively determine light transmittance.
- the micro processor starts reading this light transmittance as well as discrimination data obtained through the magnetic heads 70, 70.
- the collection of discrimination data is continued until the bill passage position sensor is turned OFF, i.e. until the bill entirely passes over the position of the magnetic head 70.
- the pull-type solenoid 74 is deactivated when a predetermined time has elapsed after the bill passage position detecting sensor has been turned ON.
- the bifurcated ends 75a, 75a of the shutter member 75 slidably in contact with the upper surface of the bill as long as it is conveyed; therefore no part of the bifurcated end 75a protrudes downward beyond the slits of the second bill feeding plate 34. Therefore, an ON state of the shutter sensor 78 is maintained as it is.
- the micro processor judges the genuineness, counterfeit or kind of the inserted bill on the basis of the collected discrimination data. If the inserted bill is genuine, the micro processor outputs a money signal corresponding to the kind of the bill to a vending or game machine. Subsequently, the DC motor M1 is driven in the forward direction for a predetermined period of time to recover the bill. Thereafter, the micro processor returns to the initial waiting condition.
- the micro processor causes the DC motor M1 to rotate in the reverse direction for a predetermined period of time to return the bill to the user. Thereafter, the micro processor returns to the initial waiting condition. In this case, the bifurcated ends 75a, 75a of the shutter member 75 enter into the slits of the second bill feeding plate 34 at the time when the opposite edge of the returning bill entirely passes over the shutter member 75. Then, the bill feeding passage 31 is closed.
- This operation is effective to surely prevent the pilferage by use of string or adhesive tape. Because, the pilferage is normally done during a limited period of time ranging from the time when the collection of genuine bill information from the inserted bill is completed to the time when the bifurcated ends 75a, 75a of the shutter member 75 are entered into the slits of the second bill feeding plate 34, that is, the stage before the pilferage of the bill by the user becomes impossible.

Abstract
Description
- The present invention relates to an improvement of a bill discrimination apparatus, more particularly to easy opening/closing operation of a bill feeding passage for the maintenance of bill discriminating means, comprising optical sensor, magnetic head, etc. disposed adjacent to the bill feeding passage or facile removal of a jammed bill from the bill feeding passage.
- The bill feeding passage in a bill discrimination apparatus normally consists of a pair of bill feeding plates disposed opposite to each other by being spaced with a predetermined gap, and is equipped with a bill conveyor means comprising belts and rollers and various detecting means, e.g. magnetic head and optical sensor, for discriminating genuine or counterfeit with respect to a bill used.
- A long term use of the bill discrimination apparatus causes contamination adhering on belts and rollers, which tends to induce bill slippage, or causes contamination on magnetic heads or optical heads which may disable the normal bill discriminating function. Furthermore, there is a possibility that the bills are jammed during conveyance through the bill feeding passage.
- Such circumstances thus force an operator to occasionally open the bill feeding passage for cleaning belts, rollers, magnetic head and optical sensors, or for removing a jammed bill.
- In order to facilitate opening/closing operation of the bill feeding passage required for occasional maintenance, there has already been proposed a bill discrimination apparatus in which one bill feeding plate is hingedly supported at its base end in order to be fixed to the other bill feeding plate at its distal end by means of a screw, e.g. a wing nut equipped with a grip. Loosening and fastening the screw by turning its grip was, however, is too time-consuming to contribute to the speeding of the opening/closing operating of the bill feeding passage for the maintenance or removal work.
- Furthermore, some other bill discrimination apparatus have been also proposed, in which one bill feeding plate is hingedly supported at its base end in order to be fixed to the other bill feeding plate in the same manner but is fixed at its distal end to the same of the other by other fixing means such as various engaging pieces or latch mechanisms. In opening the bill feeding passage, however, such conventional apparatus requires an operator two different motions: one is to rotate a swing lever provided on the fixed bill feeding plate and the other is to lift up the swingable bill feeding plate. (For example, refer to Japanese Patent Publication No. SHO 62-215461 whose counterpart application is the United States Patent No. 4,809,966 or Japanese Patent Publication No. HEI 3-10156 whose counterpart application is the United States Patent No. 4,678,072.) Any of these is characterized in that two different operating motions, i.e., releasing the swingable bill feeding plate from the fixed bill feeding plate and opening the swingable one about the fixed one, require an operator using both hands at the same time, because these two motions are not incorporated with each other. Therefore, troublesome cooperative labor is required to open the bill feeding passage.
- Thus, the object of the present invention, in view of above-described problems or disadvantages of the prior arts, is to provide a bill discrimination apparatus which is capable of easily opening or closing the bill feeding passage with simple one-motion operation.
- In order to accomplish the above object, a first aspect of the present invention provides a bill discrimination apparatus comprising:
first and second bill feeding plates confronting each other to form a bill feeding passage having a predetermined clearance therebetween;
a bill conveyor means equipped in said bill feeding passage and a detecting means for discriminating a bill conveyed by said bill conveyor means; wherein
said first bill feeding plate is hingedly supported at its base end on said second bill feeding plate;
a bill feeding plate opening lever is hingedly supported with a shaft on the swingable end of said first bill feeding plate, urged in the same direction as the closing direction of the first bill feeding plate and provided with an engaging hook at its one end and an operating projection at the other end; and
an engaging piece engages with the engaging hook of said bill feeding plate opening lever so that said first bill feeding plate can be positioned to form said bill feeding passage. - Furthermore, a second aspect of the present invention provides a bill discrimination apparatus comprising:
a swing unit, whose casing containing a bill discriminating means and having a bottom surface formed into a first bill feeding plate, being swingably supported on an exterior member forming a main body;
a second bill feeding plate being fixed to said exterior member;
said swing unit being cooperative with said second bill feeding plate to form a bill feeding passage having a predetermined clearance therebetween when said swing unit is swung to make said first bill feeding plate confront said second bill feeding plate;
an opening lever swingably supported at a distal end of said casing and having an engaging hook at one end thereof and an operating projection at the other end thereof;
un urging means for urging said opening lever in the same direction as a closing direction of said casing;
said operating projection is provided in such a manner that said opening lever causes a swing motion in a reverse direction against urging force of said urging means when a force for opening said swing unit is given to said operating projection; and
an engaging piece, provided on said exterior member, being engaging with said engaging hook of said opening lever to prevent said swing unit from swinging so that said first and second bill feeding plates form the bill feeding passage. - Moreover, in accordance with a third aspect of the present invention, said opening lever includes an almost rectangular base plate, extension arms extending forward from right and left sides of the base plate, a plurality of bearing pieces extending toward said casing from above said base plate, and an operating projection projecting far from above said casing in the direction reverse to the direction of said casing; and said extension arm has a lower end being formed into said engaging hook protruding toward said casing. The third aspect of the present invention further comprising: a shaft laterally provided in said casing at a place adjacent to said distal end for rotatably supporting said bearing pieces; and a spring wound around said shaft for urging said engaging hook at the lower end of the extension arm of the bill feeding plate opening lever toward said casing.
- Still further, in accordance with a fourth aspect of the present invention, said engaging hook has a tapered guide surface so that, when said swing unit is closed, said opening lever rotates in the reverse direction against urging force of said spring.
- In accordance with the present invention, when the opening lever of the first bill feeding plate is pulled up, the opening lever rotates about its hinge shaft in the reverse direction against urging force of the spring. And, the engaging hook provided at the other end of the operating projection is disengaged from the engaging piece. Further pulling the opening lever causes the first bill feeding plate to start a swing motion in its opening direction to open the bill feeding passage.
- In closing operation, the first bill feeding plate is pressed down from its opened position to a closed position, in which first and second bill feeding plates confront each other maintaining a predetermined gap. In this closed condition, the engaging hook of the opening lever engages with the engaging piece with assistance of the urging means which urges the opening lever in the same direction as the closing direction of the first bill conveyor plate. Thus the first bill feeding plate is fixedly maintained to form the bill feeding passage.
- Consequently, in accordance with the bill discrimination apparatus defined by the present invention, one of bill feeding plates constituting the bill feeding passage has a base end being swingably supported on the other bill feeding plate and a distal end provided with an opening lever urged in the same direction as the closing direction of this swingable bill feeding plate. And, an engaging hook is provided at one end of the opening lever to engage with an engaging piece provided on a fixed main body of the apparatus. Accordingly, the bill feeding passage can be surely opened by a simple manipulation, simply pulling the operating projection towards the opening direction of the bill feeding plate.
- The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description which is to be read in conjunction with the accompanying drawings.

gear case 48 accommodating various power transmitting means is fixed through abracket 49 to the reverse side of the secondbill feeding plate 34. The DC motor M1 is attached beneath thegear case 48 in such a manner that its rotational shaft is inserted inside thegear case 48 from the bottom. - The rotational shaft, inserted inside the
gear case 48, is fixed to apinion gear 50, which meshes with alarge diameter gear 51a of a steppedspur gear 51 rotatably supported in thegear case 48. The steppedspur gear 51 includes asmall diameter gear 51b integrally formed together with thelarge diameter gear 51a. Thesmall diameter gear 51b of the steppedspur gear 51 meshes with anotherspur gear 52 rotatably supported in thegear case 48. Aworm gear 53, provided coaxially with thisspur gear 52, rotates integrally with thespur gear 52. Adrive shaft 55, having both of its ends fixed with the drive timing pulleys 38, 38, is inserted into thegear case 48 so as to be rotatable but not slidable thereround. Thisdrive shaft 55 has aworm wheel 54 fixed at about the center thereof, which meshes with theworm gear 53. - The
drive timing pulley 38, fixed to one end of thedrive shaft 55, has an outside connected to a largediameter spur gear 56 which rotates together to thedrive timing pulley 38. Thebracket 49 has abent portion 49a, on which ashaft 57 is mounted. Thisshaft 57 rotatably supports a puncheddisk 58 which is coaxial and integral with asmall diameter gear 59. Thissmall diameter gear 59, disposed on the puncheddisk 58 which is rotatably supported on theshaft 57, meshes with thespur gear 56. The puncheddisk 58 has a plurality ofslits 60 opened thereon in a circumferential direction at equal intervals as shown in Fig. 5(b). Moreover, this puncheddisk 58 is positioned close to arotational speed detector 61 in such a manner the puncheddisk 58 interposes between a light emitting element and a photoelectric converter housed in therotational speed detector 61. Thebracket 49 supports thisrotational speed detector 61. - Accordingly, an actuation of the DC motor M1 causes a rotation of the
pinion gear 50, whose rotation is transmitted to theworm gear 53 through thelarge diameter gear 51a andsmall diameter gear 51b of the steppedspur gear 51 and thespur gear 52. Then, the rotation of theworm gear 53 is transmitted to theworm wheel 54 to rotate thedrive shaft 55, thereby causing a rotation of thedrive shaft 55 and each drive timingpulley 38 fixed on thedrive shaft 55. Thedrive timing pulley 38 cooperates with the driven timingpulley 37 to rotate anendless timing belt 39 wound around them. - In this case a rotation of the
spur gear 56, integrally rotating with thedrive timing pulley 38, is transmitted through thesmall diameter gear 59 to the puncheddisk 58. This puncheddisk 58 rotates at a predetermined rotational speed proportional to that of thedrive timing pulley 38. Therefore, the rotational speed detector generates a rotational position detecting signal each time thedrive timing pulley 38 rotates a predetermined amount. - Returning to Figs. 2 and 3, a pair of
pinch rollers bill feeding plate 34 between the driven and drive timing pulleys 37, 38. Thepinch rollers rollers bracket members sleeve bill feeding plate 34, as shown in Fig. 3. Eachpinch roller 41 is always urged to protrude from the upper surface of the secondbill feeding plate 34 by means of aspring 43, which is interposed between theplate 46 and thebracket member 44. Theplate 46 is spaced providing a predetermined distance from thesleeve 45 and fixed to the reverse side of the secondbill feeding plate 34. - Furthermore, the second
bill feeding plate 34 has rectangular throughholes bracket members holes pinch rollers bill feeding passage 31 by being urged with thesprings holes bracket members bill feeding plate 34, so that the protruding amount of thepinch roller 41 can be suppressed within a predetermined range. - A
supporter 47, around which thespring 43 is wound, is integrally fixed to the bottom surface of thebracket member 44 to prevent the dislocation. The lower part of thesupporter 47 extends through theplate 46 and moves together with thebracket member 44 in an up-and-down direction. - A
reference numeral 62 represents a power transformer; areference numeral 64, a bracket which fixes thepower transformer 62 on thebottom plate 6; and a reference numeral 63 (refer to Fig. 2), an electric power board which distributes electric power to various components such as DC motor M1 and detectors. As these electric components are well known, explanations of their constructions and functions will be omitted here. Thebracket 64 and theelectric power board 63 are fixed from inside throughscrews insulation spacer 66 onto thebottom plate 6. - Next, with reference to Figs. 6(a) and 6(b), an exterior of the
swing unit 8, including the firstbill feeding plate 33 as one component, will be explained. Theswing unit 8 comprises atray casing 67 made of synthetic resin material as shown in the drawing. The bottom portion of thiscasing 67 forms the previously described firstbill feeding plate 33. By the way, Figs. 6(a) and 6(b) are plane and right side views simply showing an appearance of thecasing 67 constituting the exterior of theswing unit 8 and schematically illustrating a mutual relationship between the firstbill feeding plate 33 and the secondbill feeding plate 34, respectively. Therefore, in these Figs. 6(a) and 6(b), illustrations of constitutional relationships with other components are omitted. - With reference to Figs. 2 and 3, various members arranged on the first
bill feeding plate 33, which is formed with the bottom of thecasing 67, will be explained in the order of their locations along the direction in which the bills are fed. First,photoelectric converters front mask 2, or in the vicinity of an inlet of thebill feeding passage 31. Thesephotoelectric converters bill feeding passage 31. - Next, two
guide rollers bill feeding plate 34. Constitutions of theseguide rollers pinch rollers bill feeding plate 34. Thus, theseguide rollers bill feeding passage 31 in the same manner as thepinch rollers guide rollers timing belt 39 wound around the driven timingpulley 37. - Next, two
magnetic heads bill feeding plate 33 in parallel with each other corresponding with the positions of thepinch rollers bill feeding plate 34. Thesemagnetic heads pinch rollers - Though not specifically shown in Figs. 2 and 3, as shown in Figs. 4(a) and 4(b), two
photoelectric converters magnetic heads bill feeding passage 31. Thesephotoelectric converter 71 constitute a part of an optical sensor serving as a bill passage position detecting sensor. - Furthermore, the second
bill feeding plate 34 is provided with two sets oflight emitting elements photoelectric converters photoelectric converters - Further referring to Figs. 2 and 3, explanation of various members disposed on the first
bill feeding plate 33 will be continued. Located a little bit downstream from themagnetic head 70 along the bill insertion direction is an automatic return pull-type solenoid 74, which is fixed through abracket 77 to thecasing 67. Thissolenoid 74 comprises an automatic return spring cooperative with its movable core. This automatic return spring allows the movable core to protrude downward when thesolenoid 74 is deactivated, while the movable core retracts when thesolenoid 74 is activated. This movable core of the pull-type solenoid 74 has a distal end fixed to ashutter member 75. Thisshutter member 75 has bifurcated ends 75a, 75a, which are fabricated through the press working and will be explained in more detail with reference to Figs. 8(a) - 8(b). - When the
solenoid 74 is deactivated, the bifurcated ends 75a, 75a of theshutter member 75 protrude into thebill feeding passage 31 through theslits bill feeding plate 33. These bifurcated ends 75a, 75a can also protrude downward below the secondbill feeding plate 34 through slits (not shown). Theshutter member 75 further includes an integrally formed shieldingplate 75b. Thebracket 77, mounted with the pull-type solenoid 74, is equipped with a pair of photoelectric converter and light emitting element cooperatively constituting ashutter sensor 78. The shieldingplate 75b is interposed between the photoelectric converter and the light emitting element of theshutter sensor 78. - Only when the bifurcated ends 75a, 75a of the
shutter member 75 pass through slits formed on both first and secondbill feeding plates plate 75b goes out of the interspace between the photoelectric converter and the light emitting element, while theshielding plate 75b comes between the photoelectric converter and the light emitting element when the bifurcated ends 75a, 75a of theshutter member 75 is between the firstbill feeding plate 33 and the secondbill feeding plate 34, or when the bifurcated ends 75a, 75a retract above theslits 76 of the firstbill feeding plate 33. - Accordingly, the
shutter sensor 78 detects the shieldingplate 75b when the pull-type solenoid 74 is activated to completely retract the bifurcated ends 75a, 75a of theshutter member 75 above theslits 76 of the firstbill feeding plate 33 and when downward movement of the bifurcated ends 75a, 75a from their retracted positions in response to the deactivation of the pull-type solenoid 74 to enter into the slits of the secondbill feeding plate 34 is prevented due to the presence of a bill and the like. On the other hand, theshutter sensor 78 does not detect theshielding plate 75b when the bifurcated ends 75a, 75a of theshutter member 75 extend downward below the slits of the secondbill feeding plate 34 through thebill feeding passage 31. - Referring now to Figs. 8(a) to 8(d), configuration of the
shutter member 75 fixed to the distal end of the movable core of the pull-type solenoid 74 will be explained. Fig. 8(a) is a plane view; Fig. 8(b), a right side view; and Fig. 8(c), a front view. However, these plane, right side, and front views respectively show only the relative positions within these and Figs. 8(a) - 8(c), and therefore it should be noted that they have no correlation with each drawing of Figs. 1 to 7. - This
shutter member 75, made of metal plate by press working, has abase plate 75c secured to the movable core of the pull-type solenoid 74 by rivet or brazing means. Previously described bifurcatedparallel ends base plate 75c to extend almost perpendicularly. Furthermore, anextension arm 75d extends from thisbase plate 75c toward the other end like a tongued piece. The front end of thisextension arm 75d is bent perpendicularly in a direction opposite to the bifurcated ends 75a, 75a to form the previously explained shieldingplate 75b. - Each of
bifurcated ends round cutouts 70a, 79b at both edges of its middle portion as shown in Fig. 8(d). At the points on both sides closer to the distal end than thecutouts round projection piece 80a and a sharp wedge-shapedprojection piece 80b. Furthermore, there is provided a dull wedge-shapedprojection 80c at the distal end of 75a. - A double dot and dash line of Fig. 8 represents an end of the movable core of the pull-
type solenoid 74. Theshutter member 75 is fixed with the movable core at substantially the center of thebase plate 75c so that theprojection piece 80b faces the bill insertion direction (the rightward direction in Fig. 2), and theshielding plate 75b faces upward (toward the shutter sensor 78). - Returning again to Figs. 2 and 3, at the place located a little bit downstream from the pull-
type solenoid 74 along the bill insertion direction, twoparallel guide rollers bill feeding plate 33, confronting the drive timing pulleys 38, 38 disposed below the secondbill feeding plate 34. These guiderollers guide rollers guide rollers timing belt - Of the various components provided on the first and second
bill feeding plates photoelectric converter 68 constitute the bill insertion sensor which detects whether or not a bill is actually inserted. On the other hand, themagnetic heads light emitting elements photoelectric converters - Referring now to Figs. 4(a) and 4(b), positional relation ship of various sensors, which are disposed on the first
bill feeding plate 33, formed by the bottom portion of thecasing 67, and the secondbill feeding plate 34, will be explained. Fig. 4 (a) is a plane view schematically showing the firstbill feeding plate 33, and Fig. 4(b) is a front view corresponding to Fig. 4(a). However, Fig. 4(b) is a schematic view showing the first and secondbill feeding plates - An
upper plate 9 is provided covering an upper surface of thecasing 67, which contains thephotoelectric converters magnetic heads type solenoid 74, to protect such electric component installed therein. A unit body including thecasing 67, various electric components housed therein, and theupper plate 9, is integrally formed as theswing unit 8 and supported abouthinge shafts bill feeding plate 33, which is the bottom surface of thecasing 67 and constitutes theswing unit 8, is allowed to approach to or separate from the secondbill feeding plate 34. - With reference to Figs. 6(a) and 6(b), an opening condition wherein the
swing unit 8 is widely opened to separate from the firstbill feeding plate 33 and a closing condition wherein theswing unit 8 is closed to form thebill feeding passage 31 between the first and secondbill feeding plates - Solid lines of Fig. 6(b) show a closed condition in which the first and second
bill feeding plates bill feeding passage 31. In this condition, as shown in Fig. 4(b), theguide rollers belts pulleys pinch rollers 41 are pressed against themagnetic heads bill feeding plates - A bill feeding
plate opening lever 82 is provided at a distal end (an opposite side of the hinge shaft 36) of thecasing 67 constituting theswing unit 8. This bill feedingplate opening lever 82 is manipulated for causing theswing unit 8 to swing about thehinge shafts bill feeding passage 31. This bill feedingplate opening lever 82, integrally formed of synthetic resin material having high elasticity and tenacity, has a lower end formed into an engaginghook 83 and an upper end formed into an operatingprojection 84. - Referring now to Figs. 7(a) and 7(b), this bill feeding
plate opening lever 82 will be further explained. Fig. 7(a) is an enlarged side view showing only essential portions of the bill feedingplate opening lever 82, while Fig. 7(b) is a rear view showing the bill feedingplate opening lever 82 itself. It should be noted that Figs. 7(a) and 7(b) have different contraction scales. - The bill feeding
plate opening lever 82 includes arectangular plate portion 85,extension arms plate portion 85, an operatingprojection 84 formed along a longitudinal direction of theplate portion 85 and extending upward and rearward from the center thereof to form an arc shape, and two bearingpieces plate portion 85 being spaced providing predetermined distance in the longitudinal direction. The engaginghook 83, formed at an end of theextension arm 86, has a taperedguide surface 88.Round cutouts plate portion 85 andextension arms - To install the bill feeding
plate opening lever 82 on thecasing 67 which includes the firstbill feeding plate 33, thecasing 67 has ashaft 90 fixed at a place slightly inside from the distal end thereof as shown in Fig. 6(a). The bearingpieces plate opening lever 82 are coupled around thisshaft 90, while theextension arms lever 82 grip both side ends of thecasing 67. As a result, the bill feedingplate opening lever 82 is rotatably installed at the swingable distal end of thecasing 67 as shown in Figs. 6(a) and 6(b). - Furthermore, a
coil spring 91 is wound around theshaft 90. Thiscoil spring 91 urges thelever 82 in a clockwise direction as shown in Figs. 6(a) and 7(a). Swing motion of the bill feedingplate opening lever 82 in the clockwise direction is restricted within a limit shown in Fig. 7(a) due to interference between thelower edge 92 of theplate portion 85 and theupper edge 93 of the distal end of thecasing 67. The right and leftside plates bill discrimination apparatus 1. In each of the insides ofside plates piece 94 which engages with the engaginghook 83 of the bill feedingplate opening lever 82 when thecasing 67 is closed to form a predetermined gap between the first and secondbill feeding plates - In more detail, when the
swing unit 8 is swung in the clockwise direction about thehinge shaft 36 until it reaches the swing limit to form thebill feeding passage 31 between the firstbill feeding plate 33 being the bottom of thecasing 67 and the secondbill feeding plate 34 as shown by a solid line of Fig. 6(b), the engaginghooks plate opening lever 82 engage with the engagingpieces side plates casing 67, i.e. the firstbill feeding plate 33, is prevented from being lifted up. In this condition, theguide rollers bill feeding plate 33 are pressed by means of spring force against the timingbelts bill feeding plate 34. Furthermore, thepinch rollers bill feeding plate 34 are pressed against themagnetic heads bill feeding plate 33, thereby enabling the insertion of a bill, automatic feeding of the bill, and reading information from the bill for discrimination. That is, normal operation of thebill discrimination apparatus 1 can be executed. - In order to remove a jammed bill or clean up various sensors and
magnetic heads 70, thebill feeding passage 31 can be widely opened by pulling up the operatingprojection 84 of the bill feedingplate opening lever 82 with one's finger to swing thelever 82 in a counterclockwise direction as shown in Figs. 6(b) and 7(a). This lifting action will not immediately be followed by the swing motion of theswing unit 8 because the engaginghooks pieces side plates - This pulling force gives the bill feeding plate opening lever 82 a rotational moment about the bearing
pieces projection 84 of the bill feedingplate opening lever 82 is positioned behind (i.e. right-hand side in Fig. 7(a)) the bearingpieces lever 82. The rotational moment acting about the bearingpieces 87 in the counterclockwise direction will cause the bill feedingplate opening lever 82 to swing in the counterclockwise direction to disengage the engaginghook 83 from the engagingpiece 94. Then, theswing unit 8 will be released from locked position, and the lifting force given to the bill feedingplate opening lever 82 comes to directly act on theswing unit 8 as a rotational moment acting about thehinge shaft 36 in the counterclockwise direction. - Consequently, the
swing unit 8 will be caused to make a swing motion in the counterclockwise direction as shown in Figs. 6(b) and 7(a). Therefore, the firstbill feeding plate 33 formed at the bottom of thecasing 67 separates from the secondbill feeding plate 34 to open thebill feeding passage 31. - In this manner, the lifting force given to the bill feeding
plate opening lever 82 not only causes thelever 82 to swing around the bearingpieces hook 83 from the engagingpiece 94 but simultaneously causes thecasing 67 to rotate about thehinge shafts bill feeding passage 31, so that releasing the engagement of the firstbill feeding plate 33 and lifting the same can be done simultaneously by simply lifting up the operatingprojection 84. - As apparent from the foregoing description, the swing center of the opening
lever 82 of the bill feeding plate is positioned at an outside (i.e. a right side in Fig. 6(b)) of thehinge shafts casing 67; the bill feedingplate opening lever 82 is swung outward to disengage the engaginghook 83 from the engagingpiece 94; the position of the operatingprojection 84 can be freely selected as long as it is positioned at an outside, i.e., right side in Fig. 6(b), of the swing center of thelever 82. - For closing the
bill feeding passage 31, theswing unit 8 is pressed downward from the opening position (a phantom line in Fig. 6(b)) as is shown in the clockwise direction in Fig. 6(b); this first cause the bill feedingplate opening lever 82 comes into contact with upper end of the engagingpiece 94 at its taperedguide surface 88. By further rotating theswing unit 8 in the clockwise direction, the taperedsurface 88 is gradually pressed by the engagingpiece 94. As a result, the bill feedingplate opening lever 82 rotates in the counterclockwise direction to cause the engaginghook 83 to ride on the engagingpiece 94. - Further rotating the
swing unit 8 will cause the engaginghook 83 to finally get over the engagingpiece 94 to automatically enters the coupling recess formed under the engagingpiece 94, being assisted by the urging force of thecoil spring 91 acting in the clockwise direction. Consequently, thecasing 67 engages with the engagingpieces 94 formed on theside plates plate opening lever 82. In this condition, thebill feeding passage 31 is formed between the firstbill feeding plate 33 constituting the bottom of thecasing 67 and the secondbill feeding plate 34 fixed to theside plates swing unit 8 for forming thebill feeding passage 31 can be carried out by the complete one-touch operation. - The closing operation of the
swing unit 8 can be executed not only by pressing down theswing unit 8 but pressing down the operatingprojection 84 of the bill feedingplate opening lever 82. In this case, the pressing force given to the operatingprojection 84 prevents the bill feedingplate opening lever 82 from rotating in the counterclockwise direction when the engaginghook 83 encounters with the engagingpiece 94. However, theextension arm 86 having high elasticity and tenacity can elastically deforms to bend rearward. Thus, the retracting motion of the engaginghook 83 and the motion of the engagingpiece 94 for reentry into the recess can be realized. - Hereinafter, an operation of the
bill discrimination apparatus 1 in this embodiment will be described briefly. When the power source of thebill discrimination apparatus 1 is turned on, a micro processor contained in thecontrol box 10 executes circuit check and initialization while the DC motor M1 is driven for a predetermined time. During this period of time, the micro processor counts the number of pulse the rotational speed signal outputted from therotational speed detector 61, in order to judge whether or not the speed of thetiming belt 39 constituting the bill conveyor means is maintained within an appropriate speed range. - An adequate bill feeding speed is guaranteed only when the value counted during a predetermined time is in an allowable range. Thus, when this condition is fulfilled, the micro processor is then conditioned to wait an insertion of a bill. On the contrary, if the counted value is out of the allowable range, the micro processor judges that the bill feeding speed is not adequate due to some king of malfunction and stops the DC motor M1 to interrupt all the operations after generating alarm. Hereinafter, explanation will be made as to the processing in the case where the adequate bill feeding speed is guaranteed.
- First, when a user inserts a bill into the
bill insertion hole 23 provided on thebezel 14 of thefront mask 2, the inside surface of theupper bezel 14a, the inclined surface of thecoupling member 25, and therib 32 formed inside thefront mask 2 cooperatively guide the front end of the inserted bill, thereby causing the bill to be fed into thebill feeding passage 31 formed by the first and secondbill feeding plates - In response to this insertion, the bill insertion sensor consisting of the
light emitting element 72 and thephotoelectric converter 68 operates to output an insertion detecting signal to the micro processor. Upon reception of the insertion detecting signal, the micro processor causes the DC motor M1 to rotate in a forward direction to initiate the bill feeding operation by thetiming belts guide rollers belts guide rollers magnetic heads light emitting element 73 and thephotoelectric converter 71 generates an ON signal. The micro processor synchronously responds to this ON signal and activates the pull-type solenoid 74 so that the bifurcated ends 75a, 75a of theshutter member 75 retract from thebill feeding passage 31. The bill insertion sensor, consisting of thelight emitting element 72 and thephotoelectric converter 68, and the bill passage position detecting sensor, consisting of thelight emitting element 73 and thephotoelectric converter 71, detect and cooperatively determine light transmittance. Then, the micro processor starts reading this light transmittance as well as discrimination data obtained through themagnetic heads magnetic head 70. - The pull-
type solenoid 74 is deactivated when a predetermined time has elapsed after the bill passage position detecting sensor has been turned ON. The bifurcated ends 75a, 75a of theshutter member 75, however, slidably in contact with the upper surface of the bill as long as it is conveyed; therefore no part of thebifurcated end 75a protrudes downward beyond the slits of the secondbill feeding plate 34. Therefore, an ON state of theshutter sensor 78 is maintained as it is. - Then, if the inserted bill entirely passes over the position of the
magnetic heads - When the inserted bill entirely passes over the
shutter member 75, the bifurcated ends 75a, 75a of theshutter member 75 enter into the slits of the secondbill feeding plate 34 due to weight of the movable core and urging force of the automatic return spring. Therefore, thebill feeding passage 31 is closed. On the other hand, if the bill is judged to be counterfeit, the micro processor causes the DC motor M1 to rotate in the reverse direction for a predetermined period of time to return the bill to the user. Thereafter, the micro processor returns to the initial waiting condition. In this case, the bifurcated ends 75a, 75a of theshutter member 75 enter into the slits of the secondbill feeding plate 34 at the time when the opposite edge of the returning bill entirely passes over theshutter member 75. Then, thebill feeding passage 31 is closed. - On the contrary, if the bill passage position detecting sensor is turned on again before the
shutter sensor 78 is turned OFF, no money signal will be outputted from the micro processor. More particularly, in such a case, after executing necessary processing similar to that in the returning operation of the counterfeit bill, the micro processor returns to the initial waiting condition. - This operation is effective to surely prevent the pilferage by use of string or adhesive tape. Because, the pilferage is normally done during a limited period of time ranging from the time when the collection of genuine bill information from the inserted bill is completed to the time when the bifurcated ends 75a, 75a of the
shutter member 75 are entered into the slits of the secondbill feeding plate 34, that is, the stage before the pilferage of the bill by the user becomes impossible. - As this invention may be embodied in several forms without departing from the spirit of essential characteristics thereof, the present embodiment is therefore illustrative and not restrictive, since the scope of the invention is defined by the appending claims rather than by the description preceding them, and all changes that fall within meets and bounds of the claims, or equivalence of such meets and bounds are therefore intended to embraced by the claims.
